针对某大型桥梁工程，提出了一种新型的钢管板桩复合地基处理方法--超深井SP法。通过各种试验验证了新方法的结构特点和可行性，建立了设计方法。在德岛-东-关城-大桥的基础上，首次应用了具有高刚性的“超级井SP”，其中一段的施工已经完成。在实际地基施工中，验证了与常规板管桩相当的工作性。在上述研究成果的基础上，JFE钢于2004年8月通过了工务研究中心的施工技术认证，成为大型桥梁的一种新的基础方法，完成了该技术的开发。
A new steel pipe sheet pile composite foundation method called "Hyper-Well SP" was developed for application to a large-scale bridge. The structural characteristics and workability of the new method were verified in various experiments, and a design method was established. "Hyper-Well SP," which features high rigidity, was applied for the first time in the foundation of the Tokushima-Higashi-Kanjo-Ohashi, and construction of one section has already been completed. Workability equal to that of conventional sheet pipe sheet piles was confirmed in the construction of this actual foundation. Based on the results of the above-mentioned study, JFE Steel received certification for examination of construction technology from Public Works Research Center in Aug. 2004 as a new foundation method for large bridges, completing the development of this technology.
